FeSiMg Cored Wire Production: Spotlight on Khorshid Alyazh Tehran Company

Introduction to FeSiMg Cored Wire

Ferrosilicon magnesium (FeSiMg) cored wire is a critical material in the production of ductile iron, also known as nodular cast iron. This type of iron is prized for its superior mechanical properties, such as enhanced tensile strength and impact resistance. This product is composed of a steel sheath filled with a mixture of ferrosilicon and magnesium, which are essential for modifying the microstructure of cast iron. This modification results in the formation of spherical graphite nodules instead of the flake-like graphite found in gray iron, significantly improving the iron’s mechanical characteristics.

Khorshid Alyazh Tehran: A Pioneer in FeSiMg Cored Wire Production

Khorshid Alyazh Tehran has earned a reputation as a leading manufacturer of FeSiMg cored wire, recognized for its dedication to quality and technological advancement. The company’s state-of-the-art production facilities and stringent quality control measures ensure that they consistently deliver high-performance products. By leveraging advanced manufacturing techniques, Khorshid Alyazh Tehran meets the demanding needs of the metallurgical industry, providing essential materials for the production of high-quality ductile iron.

Production Process at Khorshid Alyazh Tehran

  1. Raw Material Selection: The production of FeSiMg cored wire begins with the selection of high-purity ferrosilicon and magnesium. Khorshid Alyazh Tehran sources these materials from reputable suppliers to guarantee the quality and consistency of the final product.
  2. Sheath Fabrication: The steel sheath, which forms the outer layer of the cored wire, is manufactured from high-quality steel strips. These strips are processed and formed into a continuous tube, ensuring uniform thickness and strength.
  3. Core Filling: The ferrosilicon and magnesium powders are blended in precise proportions to create the core mixture. This mixture is then meticulously filled into the steel sheath, ensuring a uniform distribution of the core materials and preventing segregation.
  4. Sealing and Coiling: After the core mixture is filled, the wire is sealed to prevent any leakage of the powdered material. The sealed wire is then coiled into spools, making it ready for shipment and use in foundries.
